Zoe: Proximity alert. Must be coming up on something.
Wash: Oh my god! What can it be?! We’re all doomed! Who’s flying this thing!? … Oh right, that would be me. Back to work.
Firefly – Episode 3 – “Bushwhacked”

Mal: What the hell?
(Inara punches him.)
Inara: Don’t you dare speak to me. Sheriff, I want this man bound by law at once. That’s assuming he hasn’t been already?
Sheriff: No one’s been bound, not yet.
Inara: Thank God you stopped them. (to Mal) Did you honestly think you could access my accounts and I wouldn’t find you? And Zoe, what would your husband say if he knew you were here?
Zoe: I… I was weak.
Sheriff: So I take it they ain’t newlyweds?
Inara: Hardly. Malcolm’s my indentured man, with three years left on his debt. I imagine we’ll have to add another six months after this little adventure.
Sheriff: (re: onlookers) You’ll have to pardon them. Don’t think a one of ’em’s ever seen a registered Companion before.
Inara: I apologize for my manner.
Sheriff: Oh, not a bit.
Inara: Should I contact my ship? Do you need to hold them very much longer?
Sheriff: Looks to me like we’re about done here. I, uh. We had some unrelated trouble. His story had kind of an odor to it.
Inara: Yes, it’s not the only thing about him that does. Thank you, very much Sheriff. (to Mal and Zoe) Come along.
Firefly – Episode 2 – “The Train Job”
Zoe: Sir, is there some information we might maybe be lacking as to why there’s an entire fedsquad sitting on this train?
Mal: Doesn’t concern us.
Zoe: It kinda concerns me.
Mal: I mean they’re not protecting the goods. If they were, they wouldn’t be letting people past ’em.
Zoe: You don’t think that changes the situation a bit?
Mal: I surely do. Makes it more fun.
Zoe: Sir? I think you have a problem with your brain being missing.
Mal: Come on. We stick to the plan. We get the goods, we’re back on Serenity before the train even reaches Paradiso, only now we do it under the noses of twenty trained Alliance Feds. And that makes ’em look all manner of stupid. Hell, this job I would pull for free.
Zoe: Can I have your share?
Mal: No.
Zoe: If you die, can I have your share?
Mal: Yes.
Firefly – Episode 2 – “The Train Job”
Mal: My thanks Wash, nice save as always.
Wash: A pleasure.
Mal: And how are our passengers?
Kaylee: They’re fine. So, what happened? Was there a terrible brawl?
Zoe: Oddly enough, there was.
Wash: Are you gettin’ my wife into trouble?
Mal: Wha? I didn’t start it! Just wanted a quiet drink.
Zoe: Funny, sir, how you always seem to find yourself in an Alliance-friendly bar come U-day, looking for a “quiet drink.”
Mal: See, this is another sign of your tragic space dementia, all paranoid and crotchety. Breaks the heart.
Firefly – Episode 2 – “The Train Job”
Lund: Hey, you gonna drink t’the Alliance wi’ me? Six years today, the Alliance sent the browncoats running, pissing their pants. Y’know, your coat is kinda a brownish color.
Mal: It was on sale.
Lund: You didn’t toast? Y’know, I’m thinkin’ you one of them independents
Mal: And I’m thinkin’ you weren’t burdened with an overabundance of schooling. So why don’t we just ignore each other, til we go away?
Lund: The Independents were a bunch of cowardly inbred pisspots. Shoulda been killed off of every world spinnin’.
Mal: Say that to my face.
Lund: I said, you’re a coward, and a pisspot. Now what are you gonna do about it?
Mal: Nothin’. I just wanted you to face me so she could get behind ya.
(Zoe decks him)
Mal: Drunks are so cute.
Firefly – Episode 2 – “The Train Job”

Mal: Zoe?
Zoe: Armor’s dented.
Mal: Well, you were right about this being a bad idea.
Zoe: Thanks for sayin’, sir.
Firefly– Episode 1 – “Serenity”
Patience: We can deal. I’ll upload coordinates for a rendezvous point outside of town.
Mal: See you in the world. (Mal ends the transmission, followed by a long pause.) I believe that woman’s planning to shoot me again.
Jayne: She meant to pay you, she’d’a haggled you down some.
Wash: Just a little effort to hide it would’ve been —
Zoe: Sir, we don’t have to deal with her.
Mal: Yes, we do.
Jayne: Here’s a little concept I been workin’ on. Why don’t we shoot her first?
Wash: It is her turn.
